RICHARD PARKER HILL, OF AUCKLAND, NEW ZEALAND.

LATCH FOR SLIDING DOORS.

Application filed. September 27, 1910.

To all whom it may concern:

Be it known that I, RICHARD PARKER HILL, a citizen of the Dominion ofNew Zealand, residing at 63 Queen street, Auckland, in the ProvincialDistrict of Auckland, New Zealand, have invented certain new and usefulImprovements in Latches for Sliding Doors, of which thefollowing is aspecification.

The invention provides an improved latch for sliding doors, such as areused on tramway vehicles, wardrobes, and the like.

According hereto a spring catch plate parallel with the door and in mostcases secured to the face thereof, has a projection at its end whichengages in a cavity in a plate fixed upon the other door, or upon thedoor frame. A handle is secured to the spring catch plate, and when suchhandle is employed to slide the door to an open position the projectionis drawn out of engagement with the recess. Upon the other side of thedoor is a pivoted handle having a projection which when the handle ispulled laterally to slide open the door pushes against the spring catchplate and thereby withdraws the projection from its recess. There may bemore than one of the spring catch plates, and a latch having two of suchmembers is illustrated in the drawing where- 1n Figure 1 is a frontelevation, of a latch for sliding doors constructed in accordance withthe invention, Fig. 2 is a rear elevation of the latch, Fig. 3 is ahorizontal sectional view on the line AA of Fig. 1, Fig. 4 is an endelevation, Fig. 5 is a sectional plan view and Fig. 6 an end elevationof a slightly modified form of the invention.

The metal plate 1 is fixed to the door 2 by screws 3 and has theprojecting spring catch plate members 4 and 5 which normally springtoward the face of the door and are connected by a cross D handle 6.

Each of the members 4: and 5 has a pro jecting catch 7 and 8respectively, upon its end and these catches when the door is closedengage in recesses 9 and 10 in a plate 11 secured to the opposing dooron when a single door is employed to the door frame. The outwardmovement of the spring me1nbers 4E and 5 is limited by the heads of thescrews 12 and 13, which screws pass through slots in the members.

When the handle 6 is pulled laterally for Specification of LettersPatent.

the purpose of opening the door, the catches 7 and 8 are drawn out oftheir recesses.

Upon the opposite side of the door is a D handle 14 pivoted in sockets15 and 16 upon a plate 17 screwed to the door and having projections 18and 19 which pass through holes in the door and which severally engagethe members 1 and 5 so that when the handle 1 1 is pulled for thepurpose of sliding the door the said members are pushed outwardly fromthe door and the catches upon them are withdrawn from the recesses.

It will be apparent without illustration, that the outward tendency ofthe catch plate members may be reinforced by a spring or springsinterposed between them and the door, and if desired, the catch platemay be carried in a mortised recess in the door instead of being securedto the face thereof.

In the modification shown in Figs. 5 and 6, the handle 14 upon the backof the door is pivoted and operates as described in connection wit-h thepreceding figures. The handle 6 upon the front of the door is alsopivoted in brackets 15 and 16 countersunk in the door and the handle hasthe projections 18 and 19 one at either end, which, when the handle ispulled to open the door, engage with the spring plate members 4 and 5and raise the catches 7 and 8 at their respective ends, clear of therecesses 9 and 10.

What I do claim and desire to secure by Letters Patent of the UnitedStates is 1. The combination with a sliding door, of a latch comprisinga flexible plate attached to the door to move toward and from a facethereof and a relatively stationary member adapted to be engaged by saidplate when the door is in closed position, two handles pivotallysupported on opposite faces of the door and each having projectionsengaging the same surface of the latch plate and adapted to move theplate to disengage the members of the latch as the handle is actuated toslide open the door.

2. The combination with a sliding door, of a latch comprising a flexibleplate attached to the door to move toward and from a face thereof and arelatively stationary member adapted to be engaged by said plate whenthe door is in closed position, two handles situated on opposite facesof the door and each adapted to directly move the plate to release thelatch when actuated to slide open the door, and a supplemental stop onthe door for limiting movement of said name to this specification in thepresence of plate to disengage the members of the1 latch two Witnesses.com orisin a two-headed in or stu rojecti ng frgm said face of t he doorand ex- RICHARD PARKER HILL 5 tending through an aperture in theflexible Witnesses:
